The man says, "Well, there was this old lady. I came out of a store and found her surrounded by a biker gang. They had taken her purse and were shoving her around, taunting and abusing her.

I got so mad I threw my bags down, fought through the crowd, and got her purse back. I then helped her to her feet. I then went up to the biggest, baddest biker and told him how despicable, cowardly and mean he was and then spat in his face".
